before the bulb atthe lower end of the article 7 is engaged by the plunger. a

Figure 8 is a similar view, but showing the bulb part flattened intoaibase by the plunger member.

p p Inthese drawings, the letterA indicates a 1 frame which is supported by thewheelsl and 2 indicates a tank slidably arranged on the basepart 3 of the frame. A platform 4 forms journaledin the front uprights 6 of the frame. A small frame 7 has the depending parts 8 thereon which are fastened to the the top of the frame and a shaft 5is shaft and said small frame 7 carries the spaced rods 9 onwhich the cross head 10 is slidablysupported, this cross head being adjusted' on the rodsby'the threaded shaft 11 which passes through a threaded opening in the'cross head and is swiveled in the frame 7 so that by turning the shaft, the cross head is moved on therods. Tubular members 12 and 13 are slidably arranged on the rods 9 and are supported bythecross piece 1Q, the

member 12 being non-rotatably supported,

while the member 13 is rotatably supported. An arm 14 extends laterally from each tubular member and themold sections 15 andlfi are removably. attached tojthe outer ends of thesefarms ltby the set screws 17, ,Thus both mold 1 sections ,can be adjusted toward and away from the plate 7 and the section 16; can be moved toward and away from the a section 15. A; springy18 tends to hold the section 16 in its outward position and a footlever 19 is provided for holdinglthe" section 16 against the section 15, this lever passing through an opening formed in the platform. A spring 20 and a Weight 21are connected with the shaft tocounterbalance the weight of the mold sections, but the weight ofthe mold sections is such as to nor mally hold the parts with the mold in the,

, tank, as shown in dotted lines in Figure 2.

The weight 21 is 'adjustablefon its arm 22 0 which is attached to one end of the shaft, the

Cir

spring 20 being attached to the other end and to a part of the upper part of the frame.

A pedal 23, pivoted at 24, and arranged at one side of the platform, is connected to an arm 25 on the shaft 5 by a link 26 so that by depressing this pedal, the parts will be moved to raised position with the mold in vertical position, as shown in full lines in the figures. A latch bar 27, connected with the shaft 5, is adapted to engage a keeper member 28 on an upright lever 29 to hold the parts in raised position, said lever being pivoted at its lower end to the lower part of the frame, as shown at 30,and having its upper end engaged by a spring 31 which tends to hold the keeper member 28 under the latch member 27, vThe upper end of the lever 29 projects above the platform so thatit can be pushed outwardly to release the latch 27 from the keeper 28. The upper end of the lever 29-is arranged adjacent the free end of the pedal 23 so that both these parts can be manipulated by the same oot. I v

A yoke member 32 is pivoted on the shaft 5 and is locatedbetween the limbs of the membcr 8 and a rod 34 passes through the yoke member and isfastenedto the bight thereof intermediate the ends of the red. A weight 35 is adjustably connected with'the rear. end of the rod'34 and a shoe'36 is connected with the front end of the rod. This shoe engages the lower end of a stem 37 slidably arranged in a tubular part 38 depending from the front end of the member 7 and a presser head 39 is carried by the upper end of the stem 37 and is arranged underthe mold. A rod 40 passes through a hole in the member 7 and through a bushing 41 carried by the member 7 and has an enlargement 42 at its lower end which rests on the bar 34. The upper end of the rod 40 is engaged by a shoe 43 on the lower end of a plunger rod 44 when the same isdevpressed against the action of its spring 45 by the operator placing his foot on the head 46 of the plunger rod. Thus when this plunger rod is depressed, the rod 40 is pressed against the rod 34, so that therod 34 is rocked and its weighted end raised and its front end lowered,fth'us permitting the stem 3? and its head 39 to move downwardly under thelaction of gravity. When pressure isre'leaseo. from thehead 36, the weight 35 will move the rod 34 to its normal position and thus raise the stem 37 and its head 39 so that said head 39 will press upon the spherical part a; of the article A in themold and thus flatten. the

sphericalpart, as shown in Figure .8, so as to form a base for the article. I

As will be understood, when the parts are in raised position, the'pedal lever19 is depressed so as to move the mold section 16 against the section. 15 and the plunger rod 44 is depressed, to permit the head 39 to drop, thus leaving the lower end of the mold open. The article is then blown in the mold in the ordinary manner and by leaving the lower end open, the spherical part a will be formed, as shown in Figure 7. The foot is then re moved from the head 46, so as to permit the weight 35 to cause the rod 34 to raise the stem 37 and its head 39 to flatten the spherical part a, as shown in Figure 8. The plunger 44 is then depressed to permit the head 39 to move away from the mold and then the pedal lever 19 is released so that the mold will open and the article can be removed therefrom. The lever 29 is then moved outwardly to cause the keeper'28 to releasethe latch" 27 and then the pedal 23 is depressed so as to rock the shaft 5 and cause the mold sections to enter the water in the tank 2.

' ing purposes. The stemof the article is hotlow and it may be formed of variousveolors and by uslng different shapes of mold sec.-

tions, various designs of stems can be formed.

It is thought from the foregoing description that the advantages and .novel features of the invention will be readily apparent.

It is tobe understood that changes maybe made in the construction and in the c ombinationand arrangement of the fsev'era'l' parts, provided that such chang'esfall 'withinthe scope of the appended claims.

What I claim is,:

1. A deviceof the class described comprising a frame, a water tank removably arranged in the bottom of the frame, a shaft journaled in the frame above the tank, a small frame carried by the shaft, rods carried by the small frame, a member slidably arrangedon each rod, an arm on each member, a mold section removably attached to each arm, a plunger member carried by the small frame, a Weighted lever pivoted to theshaft and normally holding the plunger member against the bottom of the mold, foot operated means for moving the weighted lever downwardly to cause the plunger member to move away from the mold,meanswhereby the n'i'oldsections can beseparated, latch means 'for normally holding the shaft in a position with the molds in a vertical position and means for rocking the shaft when the-latch me'ans' are released to ,permit the mold sections to drop into the tank. a
